<p>384,426. Rollers for drawing, spinning, and like machines. COOK, H., 6, Tennant Street, West Bowling, and OGDEN, W., 29, Undercliffe Street, both in Bradford, Yorkshire. Nov. 26, 1931, No. 32771. [Class 120 (ii).] In drawing, spinning and like rollers comprising the combination of a boss B and an unbroken ring C of cork or cork composition, the ring is smaller than the external boss and is forced on to the boss and attached thereto by cement. The face of the roller boss may be knurled or may be covered with fabric, canvas or the like to form a key for the cement and the edge B<2> of the boss is chamfered to help the forcing on of the ring. This is performed by a machine comprising a stand A, Fig. 4, with an arm A<1> mounted on an upright A<2> and carrying a member A<3> to engage one end of the axle B3 of the roller. A member A<4> attached to the stand and downwardly movable against spring pressure engages the other end of the axle and is surrounded by a cup-shaped ring R of suitable section adapted to carry the cork &c., ring C. The ring R may be heated. A rod D with stops D<1>, D<2> regulates the movement of the arm A<1> which is operated by a lever L through links L<1>, L<2> against the action of a spring S. Specifications 215,303 and 284,598, [both in Class 120 (ii), Spinning, twisting, &c.], are referred to.</p> |
